As a child, my son, used to be an Astronaut in morning, a Scientist at noon and a Bus-conductor at night. Film actors can also have fun playing a poor man in morning shift and a billionaire in the night shift. But fundamental particles (Quarks, Leptons and Force-carrier Bosons) can have no such fun.Its clear that non-fundamental particles with inner structure of fundamental particles, can decay into other non-fundamental particles just by rearrangement of inner structure of fundamental particles. But how can fundamental particle decay into another, unless they have inner structure - i.e. it is not a fundamental particle. A Muon (a fundamental lepton) has been observed to decay into a mu-neutrino + an electron and a positron - all three fundamental leptons of different families.Scientists have a tortuous explanation. They say that initially muon decays only to mu-neutrino and a ghost-transient W-minus boson. This eases the dilemma halfway, since mu-neutrino and muon are associated particles of same family of Lepton. W-boson is only a force-carrying particle which finally decays into electron and positron. I think this only begs the question.To me this muon decay is an indication that muon is not a fundamental particle, but has a structure of more fundamental particles, which gets rearranged/ broken-up to emerge as three different particles.May I draw your attention to my post of 18th Sep "The More it Changes...", which gives detailed reason why fundamental particles cannot undergo transformations/decay.
